Head Install complete Well, after four gruelilng days of battling this task myself, I finally got the LS6 heads installed along with replacing the lifters. It started right up with no issues. The only thing now is that there is a small amount of coolant leaking from the damn front colant pipes going from head to head. Has anyone else ran into this problem and can it be fixed easily. I drove it home from my friends house (22 mi) and it has seem to stop a little. Im wondering if it will just plug itself up on its own in a couple of day. Well, at least the hard part is over...... It feels pretty damn good. I also replaced my motor mounts, they were shot. They just fell out of the clam shell...... 
EDIT: Is it normal for it to be smoking a little bit at idle. After I drive it there is no smoke?? I think I need to retune it.

Congrats!! 
You can try some High Temp silicone sealant (Think it's in a black tube). That should help keep the leak under control. I know some of the coolant tubes had some sort of washer type gasket(At least my 98 did), the new one that replaced it had a rubber gasket.

I reused the gaskets from the other heads and I torqued them down pretty good. I will see how it goes in the next couple of days. I will probably just RTV it.

I figured out why it was leaking coolant. My dumb *** forgot to put the washer with the little gasket on it. I thought I had. They were still on the old heads. Well that was a quick fix and now the car is going strong!!!!

These heads were not ported so the rockers arent an issue. I am not running open headers anymore. I just did that to have a little clip of it. Im thinking it might be that it needs a tune also. It is wasting a little more gas than usual. I just dont want this to become a big issue with my DD.
